- For the purpose of this standard, the following definitions shall apply:

ARCHITECTURAL COATINGS are any coatings applied to stationary structures and their appurtenances, to mobile homes, to pavements, or to curbs.

COATING is a material which is applied to a surface in order to beautify, protect, or provide a barrier to such surface.

FLAT COATINGS are coatings that register a gloss of less than 5 on a 60-degree meter and less than 10 on an 85-degree meter.

INDUSTRIAL MAINTENANCE COATINGS are coatings, including primers, sealers, undercoaters, intermediate coatings and topcoats, formulated for or applied to substrates, including floors, that are exposed to one or more of the following extreme environmental conditions:

  • immersion in water, wastewater, or chemical solutions (aqueous and non-aqueous solutions), or chronic exposure of interior surfaces to moisture condensation;
  • acute or chronic exposure to corrosive, caustic or acidic agents, or similar chemicals, chemical fumes, chemical mixtures, or solutions;
  • repeated exposure to temperatures in excess of 250 degrees Fahrenheit;
  • repeated heavy abrasion, including mechanical wear and repeated scrubbing with industrial solvents, cleaners, or scouring agents; or
  • exterior exposure of metal structures.

NONFLAT COATINGS are coatings that register a gloss greater than 5 on a 60 degree meter and a gloss of 10 or greater on an 85 degree meter.

CLEAR WOOD FINISHES are clear and semi-transparent coatings, including lacquers and varnishes, applied to wood substrates to provide a transparent or translucent solid film.

DRY-FOG COATINGS are coatings which are formulated only for spray application so that when sprayed, overspray droplets dry before falling on floors and other surfaces.

FIRE-RETARDANT COATINGS are coatings labeled and formulated to retard ignition and flame spread, that has been fire tested and rated by a testing agency approved by building code officials for use in bringing building and construction materials into compliance with federal, state and local building code requirements. The fire retardant coating shall be tested in accordance with ASTM Test Method E 84-99, incorporated by reference in paragraph (e)(4) or listed by Underwriter's Laboratories, Inc. as fire-retardant coatings with a flame spread index of less than 25.

FLOOR COATINGS are opaque coatings that are formulated for or applied to flooring; including but not limited to decks, porches, gymnasiums, and bowling alleys, but do not include Industrial Maintenance Coatings.

HIGH-TEMPERATURE INDUSTRIAL MAINTENANCE COATINGS are industrial maintenance coatings formulated for or applied to substrates exposed continuously or intermittently to temperatures above 400 degrees Fahrenheit (205 degrees Centigrade).

LACQUERS are clear or pigmented finishes, including lacquer sanding sealers, formulated with nitrocellulose or synthetic resins to dry by evaporation without chemical reaction. The dried film can be re-dissolved by the original solvent.

METALLIC PIGMENTED COATINGS are coatings, excluding roof coatings, containing at least 0.4 pounds per gallon (48 grams/liter) of coating, as applied, of elemental metallic pigment (excluding zinc), mica particles or any combination of metallic pigments and mica particles.

MULTI-COLOR COATINGS are coatings which exhibit more than one color when applied and which are packaged in a single container and applied in a single coat.

PRE-TREATMENT WASH PRIMERS are coatings which contain a minimum of 1/2 percent acid, by weight, applied directly to bare metal surfaces to provide necessary surface etching.

PRIMERS are coatings applied to a surface to provide a firm bond between the substrate and subsequent coats.

QUICK-DRY ENAMELS are non-flat coatings which comply with the following:
(A) Shall be capable of being applied directly from the container by brush or roller under normal conditions, normal conditions being ambient temperatures between 60°F and 80°F;
(B) When tested in accordance with ASTM D 1640 they shall: set-to touch in two hours or less, dry-hard in eight hours or less, and be tack-free in four hours or less by the mechanical test method.

QUICK-DRY PRIMERS, SEALERS, AND UNDERCOATERS are primers, sealers, and undercoaters which are intended to be applied to a surface to provide a firm bond between the substrate and subsequent coats and which are dry-to-touch in one-half hour and can be recoated in two hours (ASTM D 1640).

RECYCLED COATINGS are coatings formulated such that 50 percent or more of the total weight consists of secondary and post-consumer coatings and 10 percent or more of the total weight consists of post-consumer coatings, and manufactured by a certified recycled paint manufacturer.

RUST PREVENTATIVE COATINGS are coatings formulated for use in preventing the corrosion of metal surfaces in residential and commercial situations.

SANDING SEALERS are clear wood coatings formulated for or applied to bare wood for sanding and to seal the wood for subsequent application of coatings. To be considered a sanding sealer a coating must be clearly labeled as such.

SEALERS are coatings applied to either block materials from penetrating into or leaching out of a substrate, to prevent subsequent coatings from being absorbed by the substrate, or to prevent harm to subsequent coatings by materials in the substrate.

SHELLACS are clear or pigmented coatings formulated solely with the resinous secretions of the lac beetle (laccifer lacca), thinned with alcohol, and formulated to dry by evaporation without a chemical reaction.

SPECIALTY PRIMERS are coatings formulated for or applied to a substrate to block stains, odors or efflorescence; to seal fire, smoke or water damage; to condition excessively chalky surfaces; to block stains such as from woods prone to extractive.bleeding; or recommended for application to highly alkaline concrete, plaster, and other cementitious surfaces. An excessively chalky surface is one that is defined as having chalk rating of four or less as determined by ASTM D-4214 – Photographic Reference Standard #1 or the Federation of Societies for Coatings Technology “Pictorial Standards for Coatings Defects”.

STAINS are opaque or semi-transparent coatings that are formulated to change the color but not conceal the grain pattern or texture.

TRAFFIC COATINGS are coatings formulated for or applied to public streets, highways, and other surfaces including, but not limited to, curbs, berms, driveways, and parking lots.

UNDERCOATERS are coatings formulated for or applied to substrates to provide a smooth surface for subsequent coats.

VARNISHES are clear wood finishes formulated with various resins to dry by chemical reaction.

WATERPROOFING CONCRETE/MASONRY SEALERS are clear or pigmented sealers that are formulated for sealing concrete and masonry to provide resistance against water, alkalis, acids, ultraviolet light, and staining.

ZINC-RICH INDUSTRIAL MAINTENANCE PRIMERS are primers formulated to contain a minimum of 65 percent metallic zinc powder (zinc dust) by weight of total solids for application to metal substrates.
